A man who was shot with a crossbow bolt as he adjusted his satellite dish on Good Friday has died, North Wales police have said.

Gerald Corrigan, 74, was struck at his home in Holyhead in Anglesey. The bolt travelled through a significant part of his upper body, narrowly missing his heart and then passing through his right arm.

Police said Corrigan died on 11 May “as a result of the horrendous injuries he sustained after being shot”.

DCI Brian Kearney said: “This is a truly shocking case and our thoughts are with Gerald’s family and friends at this very sad time. The family continue to be supported by specially trained family liaison officers.”

His family issued a statement after what they called a “shocking incident”, saying they could not think of anyone who may have wanted to harm him.

The force said it is continuing to investigate the circumstances surrounding the incident.

Police have previously said one line of inquiry is that Corrigan may have been accidentally shot by a lamper – a rogue night-time hunter who uses bright lights to target animals.

Corrigan worked as a lecturer in photography and video in Lancashire before retiring to Anglesey more than 20 years ago. He had a keen interest in nature.

Anyone with information relating to the investigation is asked to contact detectives at Llangefni CID on 101 via the live webchat quoting reference number X052857 or by calling Crimestoppers anonymously on 0800 555 111.
